Whoopie, when are they going to recall the potentially deadly lag/leap and surge problems?
Even with the fuel pump replaced you will likely have the the surge or lag/leap problem sooner than later. The rotor of the alternators are defective. HD service departments have begun examining the "teeth" on the [front] of the rotor. They are looking for broken, chipped or defective "teeth". The problem is most dealers don't have the special tool to pull the rotor to examine the back side. The back side is where the problem seems to be most of the time. The key-way in the rotor that keeps the rotor inline with the shaft becomes wallowed out due to poor quality metal and poor quality fitment. This alignment does have something to do with the timing sensor pick-up - so as it gets sloppy so does your timing.
Once the dealer locates this problem your problem has only began. HD doesn't have any replacement rotors. Or at least that's their story. The fact seems to be the Chinese manufacture can't fix the poor quality metal fatigue problem and there are no replacement parts available. All the low quality production parts are going into new build at the assembly plant.
Like any other 3rd world QC they just hope it doesn't fail until after your warranty expires. If it does, so what, bring it back and they give you another - kinda like what you experience when you by Chinese junk at Walmart and it breaks.
